Who requires LH supplementation?
All patients?
Advaced reproductive age?
Hyporesponders?
Pharmacogenomics?
Antagonists?

No significant differences between the two stimulation protocols in terms of implantation, pregnancy, and ongoing pregnancy rates in patients aged <36 years old
The implantation rate was significantly better in those patients given rFSH + rLH in the 36 to 39 years old age group. Clinical and ongoing pregnancy rates were also better in this group, but not statistically significant.

Remohi, M.D. And Antonio Pellicer, M.D.
At least two of the following three features must be present:
• Advanced maternal age (≥40 years) or any other risk factor for
POR (Turner syndrome, X-fragile mutations, hystory of
chemotherapy etc.)
• A previous poor ovarian response (POR) (≤3 oocytes with a
conventional stimulation protocol);
• An abnormal ovarian reserve test (i.e., AFC 5–7 follicles or
AMH 0.5–1.1 ng/ml).
o Two episodes of POR after maximal stimulation are sufficient to define a patient
as a poor
responder;
o Patients over 40 years age with an abnormal ovarian reserve test should be
more properly defined
as expected poor PORs patient. Human Reproduction, 2011

Hypo-response to rFSH
• Hypo-responders are women with normal ovarian reserve who can achieve ‘adequate’ number of oocytes retrieved and oestradiol production
BUT… There is an increase in the cumulative
rFSH dose (i.e. >3000 IU) and in the stimulation length

Use of LH and pregnancy
CONCLUSION
• RCTs and one meta-analysis have demonstrated that recombinant LH (rLH) supplementation
does not improve neither ovarian response nor outcome of IVF in patients treated with GnRH-
analogues
• There is evidence (RCTs and one meta-analysis) that women with ‘ovarian resistance’ (hypo-
response) to rFSH benefit from rLH supplementation (irrespective of basal and post-GnRH-a
LH levels) – Hypo-response: high consumption of FSH in a previous cycle or initial slow
response to standard rFSH doses despite “normal” ovarian reserve
Common LH polymorphism is associated with hypo-response:
pharmacogenetic bases for personalizing controlled OS protocols
(higher FSH doses - LH supplementation)
• Evidence (RCTs, stratification analysis from RCTs and meta-analysis) suggesting that rLH
improves outcome of IVF in women 36 – 39 years old
• Efficacy of rLH in antagonist cycles to be proven in larger RCT (evidence of significant
increase in Estradiol levels and number of mature oocytes)
• No evidence that rLH is useful in poor responders (women with reduced ovarian reserve)
